General notes on working with imc CANSAS modules 117

Baud rate: All imc CANSAS-modules in a rack must have the same Baud rate. If even only one of the

modules or the PC is set to a different Baud rate, the CAN-Bus will not work. The CAN-controller

components detect a bus-error and deactivate themselves. The CAN-Bus is programmed to do this.

It is recommended that you work with only a single Baud rate within the test location or environs

for which task the imc CANSAS-modules are places in the racks. Only then is it possible to freely

combine modules, to insert them into racks and to have them automatically recognized by the user

interface. The setting Standard- or Extended identifier should also be the same for all.

Master / Slave-ID: Along with the Baud rate, a single Master- and Slave-ID should also be set for all

the imc CANSAS-modules. Like the Baud rate, these two CAN-Bus identifiers absolutely should be

the same throughout the measurement setup. The two identifiers enable the user interface to find

any imc CANSAS-modules connected to the CAN-Bus and to make settings for them. When imc

CANSAS-modules are first integrated into the system, always enter these two IDs along with the

Baud rate. It is also only possible to find modules in the system with these identifiers. In this case it

is desirable and even necessary that the same CAN-identifier is set for all modules. Note that for

sending measurement values along the CAN-Bus it's exactly the other way around: in this case, all

identifiers absolutely must be different (unique), for the CAN-Bus to operate.

Major customers / Factory-set Baud rate: By default, imc CANSAS-modules are shipped with a Baud

rate of 125k and Master/Slave ID 2032 and 2033. For major customers, the rack-operation

alternative is available: Baud rate 500k and ID 2 and 3. This combination is especially recommended

for operation in racks. If you are a major customer, arrange with our Sales personnel for all your imc

CANSAS-modules to be pre-configured for rack operation. Then you can immediately employ virgin

modules in your rack.

3.5.5.3 Rack maintenance

The rails in the 19“-subrack gradually become worn down and require a certain amount of maintenance.

If it becomes difficult to insert or remove modules, then it's possible to lubricate the rails with such

substances as Vaseline. Feel free to contact our Customer Service for suggestions.
